FAN ANTI-CORROSION STRUCTURE

摘要

A fan anti-corrosion structure includes a base seat, a circuit board and at least one coating unit. The base seat has a sidewall and a bearing cup. A rest face extends from the sidewall toward the bearing cup. The circuit board is fitted around the bearing cup and disposed on the rest face. A closed space is defined between the circuit board and the base seat. The coating is coated on the circuit board. The circuit board is protected from the corrosion of the moisture and the salt fog by the coating unit and the closed space. Also, the cost of the mold for forming the coating unit is saved to lower the manufacturing cost.

1. A fan anti-corrosion structure comprising:
a base seat having a sidewall, a bearing cup extending from the base seat, at least one rest face extending from the sidewall toward the bearing cup; a circuit board fitted around the bearing cup and disposed on the rest face, a closed space being defined between one face of the circuit board and the base seat; a stator assembly including multiple silicon steel sheets, the stator assembly being fitted around the bearing cup and disposed on the circuit board; and at least one coating unit coated on the other face of the circuit board, which face is distal from the base seat.
